Authorities in southeastern Wisconsin called off the search for a 43-year-old armed man involved in a domestic disturbance Tuesday.  Witnesses say Jonathan Pogreba pointed a gun at his wife during an argument.  She had just filed for divorce.  The couple’s 16-year-old son reportedly fired at least three shots from a shotgun in the man’s direction, possibly hitting him once.  Officials say the search was called off at sunset due to the danger of looking for an armed man in the darkness.  Because of the Tuesday incident, classes in the Palmyra-Eagle Area School District were called off — but they will resume Thursday.
